Despite hating each other on WWE television, Rey Mysterio is proud of what Dominik Mysterio has accomplished in his career so far. Mysterio recently broke character to reveal Dominik's "love letter" to the late, great Eddie Guerrero. Latino Heat passed away 20 years ago on November 15, 2005. To remember his best friend, Rey wrote an emotional letter to Eddie on The Players' Tribune. One of the things the 50-year-old legend talked about was Dominik Mysterio and how he has turned into one of the best young WWE Superstars today. He took shots but also praised and bragged about his son to Eddie Guerrero, detailing the things he has done since making his debut in 2020. "The wrestler he is now, it feels like a love letter to so many of the things that made YOU so special. He has the presentation down perfect: the sleazy (no offense) stache, the terrible (no offense) mullet, the ugly (no offense) jewelry and clothes. He’s got the s***-eating grin. He’s got that innate ability to play off different people (like you did with me, Batista, Chyna and so many others). And I’ll tell you the number one trait of Dom’s that’s a love letter to you, Eddie — and I bet you already can guess what I’m about to say here, too. THE WORSE HE BEHAVES??? THE MORE THEY CHEER. As you know, it’s harder to pull this off than it looks: To be a bastard (no offense) who the fans want to embrace, flaws and all … because even at your worst, they can see something human at the center. But that’s what Dom has been able to achieve," Rey wrote. Five years into his career, Dominik Mysterio is already being talked about as a future world champion by stars like Cody Rhodes. Dominik just lost his Intercontinental Championship to John Cena, but he's still the reigning AAA Mega Champion. Former WWE Champion touts Dominik Mysterio to win a world title in the next 5 yearsBig E revealed his thoughts on Dominik Mysterio's future in an episode of the RAW Recap in late September. It wasn't on the cards early on, but Dom's improvement was so evident that it's hard to deny his potential as a future world champion."The thought of putting the label ‘future world champion’ on Dominik Mysterio three years ago, four years ago, [was] laughable. I’d laugh you out [of] the building. But now, is this outside the realm of possibility? Not at all. In fact, I would be surprised if Dominik Mysterio doesn’t hold a world championship within the next five years," Big E said.The former WWE Champion had high praise for Dominik, who has carved out a role as one of the biggest heels in pro wrestling today.
